개찰구 means a ticket gate or turnstile, especially at a subway or train station.

It breaks down like this:

• 개찰 = ticket inspection/checking
• 구 = gate/opening

So 개찰구 앞에 means in front of the ticket gate.

This is a very common question.

• 앞에 means at/in front of
• 앞에서 often means at/in front of, and that is where an action happens

In this sentence, 앞에 marks the location where there were many people:

• 개찰구 앞에 사람이 많아서 = There were a lot of people in front of the ticket gate, so...

If you said 개찰구 앞에서, it would sound more like the action itself happened there:

• 개찰구 앞에서 기다렸어요 = I waited in front of the ticket gate

So 앞에 is natural here because it connects more directly with 사람이 많다.

Here, 에 marks a location where something exists.

Since the sentence says 사람이 많다 (there are many people / it is crowded with people), Korean often uses 에 for the place where something is present.

So:

• 개찰구 앞에 사람이 많다 = There are many people in front of the ticket gate

This is similar to how Korean uses 에 with existence verbs like 있다:

• 학교에 사람이 많아요 = There are many people at school

이/가 is often used when identifying what exists or what is in a certain state.

Here, 사람이 많다 means:

• there are a lot of people
• people are many

Using 이/가 is the most neutral and natural choice.

If you said 사람은 많아서, it would sound more contrastive, as if you were saying something like:

• As for people, there were many...
• There were many people, but...

So 사람이 많아서 is the normal wording here.

많아서 is the connective form of 많다 (to be many / to be a lot).

The ending -아서/어서 often means:

• because
• so
• sometimes just a natural sequence

Here it gives a reason:

• 사람이 많아서 조금 기다렸어요 = Because there were a lot of people, I waited a little

So 많아서 connects the cause and the result.

많다 is a descriptive verb/adjective in dictionary form.

To connect it with -아서/어서, you remove 다 and add -아서:

• 많다 → 많아서

Because the stem vowel is ㅏ, -아서 is used rather than -어서.

A few similar examples:

• 작다 → 작아서
• 바쁘다 → 바빠서
• 좋다 → 좋아서

Not always.

It can mean:

1. because / since
2. and then / so, showing a natural sequence

In this sentence, it is clearly giving a reason:

• There were many people, so I waited a bit

So translating it as because or so both works well.

Because the sentence is describing a completed past event:

• there were many people
• so the speaker waited

기다렸어요 = waited

It comes from 기다리다 (to wait):

• 기다리다
• 기다렸어요

This is the polite past form.

Both mean waited, but the politeness style is different.

• 기다렸어요 = polite, conversational, common in everyday speech
• 기다렸습니다 = polite, more formal, often used in speeches, announcements, formal writing, or very formal situations

In normal conversation, 기다렸어요 sounds natural.

조금 means a little or for a short time.

In this sentence:

• 조금 기다렸어요 = I waited a little / I waited for a bit

It softens the statement and suggests the wait was not very long.

Here it is mainly about time.

Even though 조금 literally means a little, with a verb like 기다리다 it usually means:

• waited a bit
• waited for a short while

So the natural interpretation is about duration.

Yes. Korean often omits the subject when it is understood from context.

So the sentence does not explicitly say I, but in English we naturally supply it:

• I waited a little

This is extremely common in Korean. If the speaker wanted to say it explicitly, they could say:

• 저는 개찰구 앞에 사람이 많아서 조금 기다렸어요.

But very often 저는 is unnecessary.

The structure is:

• 개찰구 앞에 = in front of the ticket gate
• 사람이 많아서 = because there were a lot of people
• 조금 기다렸어요 = I waited a little

So the overall pattern is:

[place] + [people were many / it was crowded] + so/because + [I waited]

Korean usually puts the main verb at the end, so the reason comes before the final action.

Yes, absolutely.

That is a very natural English rendering.

Even though the Korean literally says there were many people, English often prefers:

• It was crowded in front of the ticket gate
• There were a lot of people in front of the ticket gate

Both capture the same idea.

Korean often expresses crowded by saying there are many people.

So:

• 사람이 많다 = there are many people
• in natural English, that often becomes it’s crowded

There is also 복잡하다, which can mean crowded, busy, or complicated, but 사람이 많다 is very direct and very common in everyday speech.

Sometimes, yes, but the nuance changes a little.

• 조금 기다렸어요 = I waited a little / for a bit
• 잠깐 기다렸어요 = I waited briefly / for a moment

Both are possible, but 조금 is a very neutral, common choice here. 잠깐 can sound a bit more specifically like for a moment.

It could, but it is not necessary.

Current sentence:

• 개찰구 앞에 사람이 많아서 조금 기다렸어요.

This already means:

• There were many people in front of the ticket gate, so I waited a little.

You could also split it into two parts:

• 개찰구 앞에 사람이 많았어요. 그래서 조금 기다렸어요.
• There were many people in front of the ticket gate. So I waited a little.

Using -아서 makes it one smooth sentence. Using 그래서 makes it two separate sentences with a clearer break.

Yes. It ends in -어요, which is the standard polite speech level used in everyday conversation.

So:

• 기다렸어요 = polite
• not casual/plain
• not highly formal

This is a very common level for speaking with people you do not speak casually with, or in normal polite conversation.
